At the present moment I have no further details concerning this insect. 
Chionaspis striata, Newst. is nearly related to ©. nudata, but the second pair of 
lobes in the former species are broad and very distinet and there also are other 
well marked differences. 
It also bears a striking resemblance to Greens (. simplex') in the morphological 
characters of the margin of the pygidium; but this species possesses seven groups 
of eireumgenital glands, in which respect it is quite unique. 
Chionaspis Bussii, n. sp. (Newstead). 
Puparium of female. Narrowly elongate, sides parallel behind the second 
pellicle; margin broadly flattened. Colour dusky ochreous to pale ochreous brown. 
Length 2,50—3 mm. Width 50—175 mm. 
Female adult. Very long and narrow; length four to four and a half times 
greater than the width. Rudimentary antennae with one or two spines; the normal 
number is in all probability two. Thoracie stigmata: anterior pair opposite the mentum 
and not far distant from it; posterior pair separated from the former by at least 
Fig. 11. Chionaspis Bussi. 
three and a fourth times the width between the anterior pair; parastigmatic glands 
apparently absent. Spiniforms squames presents on the last two free abdominal 
segments. Pygidium with five groups of circumgenital glands; formula of 3 examples:

doubtful. Dorsal pores absent from the middle area; but there are 10—11 near 
the margin, all of which are much smaller than the marginal ones. Margin of 
pygidium (fig. 11) with three pairs of well developed lobes; second and third pair 
duplex and somewhat wedge-shaped, the upper lobule of each being the smallest. 
Squames spiniform; there is a single one immediately anterior to all of the lobes; 
the second one lying almost transversely across the upper lobule of the 
second pair of lobes. Median pair of spines nearly equal in length to the 
median lobes. 
The morphological characters of this insect are in many respects like those of 
Chionaspis acuminata, Green?). It is distinguishable from Greens species by the
